ABSTRACT:
In one embodiment, a carrier-managed system such as the cellular network or the Global Positioning System (GPS), is leveraged to directly determine or triangulate geographic locations of the dual mode device and then the access point. Advantageously, a service provider may constantly and automatically update its database with the geolocation of APs and associated devices to thereby provide accurate information and improved emergency services.
